摘要：

A photoelectron spectroscopic method is proposed to estimate the ratio of number densities between the monomer and the dimer produced in the supersonic jet. Approximate monomer-dimer ratios have been estimated for water, methanol and formic acid by assuming that the photoionization cross sections of the monomer and dimer are equal to each other. The results show reasonable agreement under similar conditions to those available from mass spectrometric analyses of fragmentation patterns. A simple temperature-controlled supersonic nozzle beam source is described here, which enables one to produce hydrogen-bonded dimers in measurable amounts.
